Topic: Three Small Wrenches. One is a Mystery. (Read 482 times)

I picked these up in a 'bay lot purchase. I bought the entire lot for one tool.i got these three smalls and other items as a bonus. A five inch Diamond No. 11. A six inch Boos Tool Corp. wrench. The third item is a five inch adjustable monkey wrench marked Pat Apd. For. No date, name or any other engraving or stamps.

It is a design patent not a standard patent, that being said I don't know the details of what distinguishes that. I guess the design patent protects the way an item looks not the way an item functions. Maybe it is easier and faster to obtain a design patent.
